How to Select the Right Rounding Machine?

What is a Rounding Machine?
As a commonly used mechanical device in the metal processing field, the rounding machine’s main function is to bend flat materials into the desired arc shape. Its structure mainly consists of components such as the frame, rotating shafts, rollers, and transmission devices. During operation, the bending of materials is achieved by adjusting the positions and heights of the rollers. The working principle of the rounding machine is based on the three – point – makes – a – circle principle. As the relative positions of the workpiece change and it undergoes rotational motion, the workpiece experiences continuous plastic deformation, ultimately obtaining the predetermined shape.

The rounding machine is a widely – applied cold – working forming equipment. It achieves shape transformation by rolling and compressing the workpiece within the equipment. Its main components include drums, motors, a transmission system, and a heating system. The drum is generally hollow, equipped with an air heater and a cooling water device inside. The motor drives the drum to rotate through the transmission system. The workpiece moves forward continuously as it rotates inside the drum, and gradually takes shape through functions such as wall friction, heat exchange, and air cooling. Thanks to its unique processing characteristics, the rounding machine is widely used in many fields such as plastics, food, pharmaceuticals, and chemicals.

Classification and Differences of Rounding Machines:
There are numerous models of rounding machines, each with different characteristics and application scopes.

According to the operating method of the rounding machine: it can be classified into manual rounding machines, hydraulic rounding machines, and CNC rounding machines.
Manual rounding machines require manual operation and are suitable for simple bending tasks. Hydraulic rounding machines operate by driving the rollers through a hydraulic system, offering higher work efficiency and accuracy. CNC rounding machines adopt a computer control system and can realize automated production line operations.

According to the specifications and capabilities of the rounding machine: it can be divided into small – sized rounding machines, medium – sized rounding machines, and large – sized rounding machines.
Small – sized rounding machines are suitable for bending smaller – sized materials like metal sheets and pipes. Medium – sized rounding machines are suitable for medium – sized materials, such as in the manufacturing of large – scale equipment parts. Large – sized rounding machines can handle large – scale structural components, such as ship hulls and large containers.

According to the functions and uses of the rounding machine: it can be divided into single – roller rounding machines, double – roller rounding machines, and multi – roller rounding machines.
Single – roller rounding machines have only one roller and are suitable for simple bending tasks. Double – roller rounding machines have two rollers and can achieve more complex bends and arc shapes. Multi – roller rounding machines have multiple rollers and can handle larger – sized and more complex – shaped materials.

According to the structure of the rounding machine: it can be divided into vertical rounding machines and horizontal rounding machines.

What parameters are needed for model selection?

When choosing a rounding machine, factors such as the material (primarily considering the hardness of the pipe), thickness, length, and shape (circular, square, rectangular), roller molds, as well as the required pipe – bending radius, accuracy requirements, and the product it will be used for need to be considered. It would be best if you could provide us with the drawings, so that we can confirm the model more quickly.
